The SunKeeper is fully protected against system faults
listed below. Recovery is automatic except where
noted below. Refer to section 3.0 for fault LED
indications.
Reverse Polarity Solar (LED OFF) – no charging,
disconnects solar module until wired with correct
polarity.
Reverse Polarity Battery (red blinking LED) – no
charging, displays fault until battery wired with correct
polarity.
Short Circuit Solar (LED OFF) – stops charging until
short clears or will enter Night stage (LED OFF) if fault
persists.
Charging Over-current (red blinking LED) –
charging current has exceeded SunKeeper current
rating; fully automatic recovery; retry every 10
seconds.
High Temperature Condition (red blinking LED) –
ambient temperature is too high; charging
automatically resumes when SunKeeper has cooled to
a safe temperature.
